Now looking for an alternate source for supplies. Been ordering stuff from AS&S for many years. For the first time, I had to return something; eight rings/seals. Bags never opened. I can't believe the amount of aggravation I'm getting trying to return them. Been trying for over a month. Of four identical rings, they eventually issued a return authorization for only three. I had also sent close up photos of the parts. I had the parts long enough that I have to pay 15% restocking, but I can't even get to that point. If you need to return something to them, it may not be as easy as you think. The reps command of the English language is not the best, so maybe that's part of the problem.
